[rdiff-backup-users] rdiff-backup remounts partition readonly?

[Christos Tachtatzis]

Hi everyone,

   I am running rdiff-backup for sometime now on a FC3 box which I
recently update it to FC4. Since the python path changed I moved all
the required libraries to the new python path and the backups start
working again smoothly. I am doing backups localy to an external usb
drive, which is mounted only when the script runs and then unmounts to
keep the backup safe.

  However today the backup failed and the error message is below. I
was monitoring /proc/mounts and the partition is mounted read-write
from the mount command but when the rdiff-backup starts it remounts
the partition as read-only.

Has anybody come accross this problem. Am I doing something wrong
here? If you need more info let me know.

Regards,
Christos
